Question

嗨，我有一个问题是隐藏在两个中间单元格上有零值的行，中间单元格上的值是从谷歌电子表格动态生成的，下面的代码是好的并隐藏行我写的零值，但是这段代码没有捕获生成的值。

我想要做的是在生成值后隐藏行？

当我尝试提醒输出时，我发现了这行中的问题

 if (cells[j].innerHTML != '0') {

代码获取此值：

<p id="B1S"></p>
<p id="B4S"></p>
<p id="B4S"></p>
0

唯一的最后一行被接受并隐藏但其他行返回不匹配的值

谢谢。

Answer 1

我解决了“感谢上帝”

使用

if (cells[j].getElementsByTagName('strong')[0].getElementsByTagName('p')[0].innerHTML != '0')

而不是

 if (cells[j].innerHTML != '0') {

这就是全部

感谢@Bardo和@Selim Ajimi的良好纠正

隐藏基于单元格值的行=零
